Abstract

Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Verbesserung der Audioqualität in einem Mobilfunknetz, womit eine endgeräteunabhängige Verbesserung der Audioqualität in Mobilfunknetzen erzielt werden soll. Die Erfindung zeichnet sich dadurch aus, dass ein Entzerrer in den einer Kommunikationsverbindung zugeordneten Audiopfad geschaltet wird, der in Abhängigkeit des/der an der Verbindung beteiligten Endgerätetyp(en) eine Beeinflussung der Audioqualität im Audiopfad vornimmt. Dadurch kann der Netzbetreiber die Charakteristika des Klangbildes seines Netzes festlegen.
